Grabbing refs

A xoid atom can be used to grab element refs (as in React's terminology) in a typesafe manner.

const $ref = atom<HTMLElement>() // Stream<HTMLElement>

$ref.set(document.body)

It's completely safe to feed atom.set calls as refs to React components as ref prop.

import { atom } from 'xoid'
import { useSetup } from '@xoid/react'
// inside React
const { $ref } = useSetup(() => {
  const $ref = atom<HTMLDivElement>()
  $ref.subscribe((element) => console.log(element))
  return { $ref }
})
return <div ref={$ref.set} />

This usage won't result in Typescript complaints. xoid's set method in this example, would be compatible with React.RefCallback.
